The childlike innocence which had given pleasure in Meyerheim and Waldmüller was now thought to be too childlike by far. The merriment which radiated from the pictures of Schroedter or Enhuber found no echo amidst a generation which was tired of such cheap humour: the works of Carl Hübner were put aside as lachrymose and sentimental efforts. When the world had issued from the period of Romanticism there was no temptation to be funny over modern life nor to make socialistic propaganda; for after the Revolution of 1848 people had become reconciled to the changed order of affairs and to life as it actually was--its cares and its worries, its mistakes and its sins. It was the time when Berthold Auerbach's village tales ran through so many editions; and, hand in hand with these literary productions, painting also set itself to tell little stories from the life of sundry classes of the people, amongst which rustics were always the most preferable from their picturesqueness of costume. At the head of this group of artists stands _Louis Knaus_, and if it is difficult to hymn his praises at the present day, that is chiefly because Knaus mostly drew upon that sarcastic and ironical characteristic which is such an unpleasant moral note in the pictures of Hogarth, Schroedter, and Madou. The figures of the old Dutch masters behave as if the glance of no stranger were resting upon them: it is possible to share their joys and sorrows, which are not merely acted. We feel at our ease with them because they regard us as one of themselves. In Knaus there is always an artificial bond between the figures and the frequenters of the exhibition. They plunge into the greatest extravagances to excite attention, tickle the spectator to make him laugh, or cry out to move him to tears. With the exception of Wilkie, no _genre_ painter has explained his purpose more obtrusively or in greater detail. Even when he paints a portrait, by way of variation, he stands behind with a pointer to explain it. On this account the portraits of Mommsen and Helmholtz in the Berlin National Gallery are made too official. Each of them is visibly conscious that he is being painted for the National Gallery, and by emphasis and the accumulation of external characteristics Knaus took the greatest pains to lift these personalities into types of the nineteenth-century scholar.
